assessment and comparison of efficacy of intra-articular prp and corticosteroid in first cmc joint oa treatment

Conditions: Thumb Osteoarthritis; Hand Osteoarthritis; Platelet Rich Plasma; Corticosteroid; Intra-articular Injection; Ultrasonography

Summary: aim: we aim to determine and compare the efficiency of single dose intra-articular (ia) platelet rich plasma (prp) and corticosteroid (cs) injections for the treatment of first carpometacarpal joint osteoarthritis (1. cmc oa) on the basis of pain, hand function and pinch strength. material and method: sixty patients meeting the criteria were included in the study. patients were randomized into group 1 (prp group) or group 2 (cs group). patients were evaluated by visual analogue scale (vas), duruoz hand index (dhi) and pinch meter for pain and function.

osteoarthritis(oa) which is the most prevalent form of arthritis, is a degenerative process eroding articular cartilage. joints affected most commonly include hand, knee, hip and spine.the trapeziometacarpal joint of the thumb (cmc) is a common source of pain due to oa. age adjusted prevalence of rhizarthrosis is reported as 5-17% in men and 7-21% in women. although the effect of the cmc osteoarthritis (rhizarthrosis) on hand function and strength have been reported, it is likely underdiagnosed in clinical practice. conservative treatment modalities range from therapy, orthoses, modification of daily activities to intraarticular injection in early stages. for patients who fail conservative measures or advanced stages, surgical treatment options are indicated. platelet-rich plasma (prp) is the processed fraction of autologous peripheral blood with a platelet concentration above the baseline. prp therapies have been used in the treatment of dejenerative joint disease and also in different fields of medicine for more than two decades. the rationale underlying the prp therapy in oa is to stimulate the tissue repair and regeneration via growth factors and bioactive molecules involved in basic pathways such as inflammation, angiogenesis and cell migration in alpha granules of platelets. the studies evaluating the theuropatic effect of prp in osteoarthritis generally include its application in the knee, hip and shoulder joints. there is very few article reporting the application of prp in rhizarthrosis. 2019 american college of rheumatology/arthritis foundation guideline for the management of osteoarthritis of the hand, hip, and knee suggests "no recommendation in regard to osteoarthritis of the hand". same guideline suggest that " intraarticular glucocorticoid injection is conditionally, rather than strongly, recommended for hand osteoarthritis. in "2018 update of the eular recommendation fort he management of hand osteoarthritis" did not mention the prp application for hand osteoarthritis. in our prospective, randomised, double-blind, clinical study we aimed to compare the results of the intraarticular application of corticosteroid and prp in early stages of the rhizarthrosis.
